Answer / sai

Because the relationship between voltage and current in a capacitor is:

i = C*dv/dt

An instantaneous change in the voltage across a capacitor would require that the rate of change of the voltage (dv/dt) be infinite, and hence the current would have to be infinite.

For inductors, the relationship is:

v = L*di/dt

In order for the rate of change of current to be infinite (instantaneous change), the applied voltage would have to be infinite.

Answer / sabaris

Generally capacitors stores the energy as voltage in magnetic field..the stored energy is directly proportional to the area and inversly proportional to the distance btwn the two metals...these two things are constant.already it charges in a linear time and discharging it in some linear time..if a sudden change will occur(i.e. vge raise or drop) there is no possibility to charge are discharge with respect to it..thats why capacitor always dont allow the sudden changing voltages...in inductor it stores the energy as current in electric field...similarly the procedure is above the same....

Answer / ganesh.k

initially capacitor behaves like a short circuit so even though v apply voltage across capacitor the vltg across it is zero due 2 short ckt condition, whereas the inductor initially acts as a open ckt so it oppose any sudden chage in current

Answer / siva

in capacitors current leads.voltage lags.so capacitor oppose the voltage
